The 10-day-old cubs were brought to the Oregon Zoo to be looked after by Michelle Schireman, who is the Cougar Coordinator for the Association of Zoos and Aquariums.

Without a mother the cubs wouldn't be able to survive on their own in the wild.

Schireman wrote on the Zoo’s website: “I work to find them suitable homes. We have a couple of options we are considering right now, and the cubs should only be in our care for a couple of weeks at the most."

The cubs are barely opening their eyes and they don't have any teeth yet, but they're eating well and sliding around the facility.

She added: “They are loud. When you come to feed them in the middle of the night, you can hear them all the way out in the parking lot."
